Coating combustion synthesis controlled by moving electron beam

The model of the coating synthesis on the substrate is suggested at the conditions of electron beam controlling. The detailed reaction scheme in the treated layer is taken into account. Reaction kinetics is described based on mass action law. Reaction retardation by solid reaction products is taken into consideration. The review of similar models, simple and coupled, is made. Asymptotical solution of the particular coupled problem with summary reaction scheme is obtained. It was found that self sustaining mode is possible when the coating is synthesized on the substrate. The example of maximal temperature establishment is illustrated for the detailed reaction scheme in the Ti-C-Al system when the conversion is initiated by electron beam. (paper)
